Why does Snapchat not work or even update on my Droid X (first generation) ?

Snapchat does not send, it closes, and it wont update. I have tried unistalling it three times. Nothing has changed. My phone is old, it is the Droid X that doesnt have the front camera. So yeah its old. But is there a reason snapchat doesnt work properly?

Welcome to Android Central! Did you install Snapchat from Google Play Store, or from somewhere else? If it was from somewhere else, it's possible that the app actually isn't fully compatible with your phone (and in that case, Google Play Store wouldn't have shown it as being available to install).
